CHARLES E. EARRINGI'ON,- OF EHILADELPHIA, PENNSYLVANAV 'j AGI ATO HANDLEQ y Application filed February 28, 1920. Serial No. 362397;

To all whom it may concem: i

Be it known that I; C ARLES' E. FARRING- TON, a 'citizen of the UnitedStates, residng at Philadelphia, in the 'county of Philadelphia andState of Pennsylvanimhave invented new and useful Improvements inAgitator Handlesof which the following is a specification. i

This invention has for its object to provide a handle for various usesbut more particularly for the employment with barrel agitators, such forinstance as illustrated in my application for Letters Patent, Serial No.251,'786, filed August 28, 1918.

The invention comprises an' arm 'which may serve as a lever for rotatinga member, such as a shaft or agitator, and a pin extendinglaterally fromthe end of the arm, which will serve as the, crank to 'be grasped bythehand. The pin is detachable from the arm, an`d, when not in use, isclamped in a groove' or slot formed in the arm, by securing the arm bysuitable fastenings a, the head of a barrel. Thus the pin m b'edismounted and secured in its clamped position when the handle as awhole is not in use or is to be shippecl. The arm; when used forefi'ecting the rotation of an ag itator, may be formed with anenlargement to serve as the cover or closure of a hole in 'the head ofthe, barrel, and may be pro vided with 'means to project into the holefor detachably engagng the end of the agitator which is located withinthe barrel.

`On the drawings,-

Figure 6 represents alongitudinal section through the arm with thecrank-pin located in its active or operative position\ i Referring tothe drawings,-I,have .illus-.

t rated in Figure 1 the upper portion of ta wooden barrel 10 havingahead 11. Within a substantially circular head 14. which serves I as acover or closure for theaperturel in v i\ thecenterof the barrel head ll. The arm 13 is formed with an angular portion ;16 connecting theheadoricap 14 with thebody ofthe arm, so that thelatterliesin aplane spacedor separatedfrom the plane of the i barrel head. The outer extremity ofthe arm hasa dependen-boss l? which termii nates short of thebarrelhead, and which has a threaded aperture 18. As shown in Figure 3, thecircularheaid' hasin itsunder facecircular groove .19 to receivea packving ring 20 .of rubberor other'suitable mai terial, and it also has ears21 which are apertured at 22, as shownin Figurea An point wequi-distantfrom the apertures 22', and through these thrceapertures 22,22, 23,

. Inasmuch as the arm andtshead maybe .utilzedto effect the rotation'ofthe agitator,

the head or cap isformedgwith depending e i clutch members which:project into the apel"- ture 15 and form a journal engagngthe wall ofsaid aperturei which serves` as a hearing `therefor. 'Said mem'berslikewise are constructed to engage" the upper; end 'of the. agitatonblade; As shownythe clutch i members may be three in number: asindicated at 24:, Qi, 25. 'The member25 'andone 'ofjthe members'24c lieon one side of the agitator blade, and the' other member 24: {lies-wonthe other-side, sothat, when the arm is rotated e e.

a clockwi sedirection,' it ;will rotate the bla e; t, he t e arm ,is`rot tedn th reverse direction, the rotation of the blade is not properlye'l'ected. The reason for this is that ordinarily the blade, toaccomplish its functions most effectively, should be rotated in aclockwise direction only. Of course, the member' 25 could be duplicatedon the opposite side of the blade, so that the blade could be rotated asreadily in one direction as in the other. The outer walls of the lugs ormembers 24-, 25, have a cylindrical curvature about a common center, soas properly to engage the cylindrical wall of the aperture 15.

The arm is provided with a crank pin by which it may be rotated, butwhich, when not in use, may benested in a recess in the arm. This pinmay take any suitable or desirable form. As shown, it consists of anelongated stud 26 andcprovided at its opposite end with a screw thread28 to enter into threaded engagementwith the aperture 18 in the end ofthe arm 13, and a sleeve 29 which encloses the stud. The constructonthue 'described permits the sleeve to be moved to an eXtended positionand to have a freedom of movement when 'it is grasped by the hand, inthe act of revolvng the stud about the aXis of' theagitator.

If the crank pin were permanently fixed to the arm,-it is evident that,in 'transporting the barrel, it would be easily broken or injured andwould prevent the close packing of the barrels, and hence the crank-pinis detachable. Iprovide for assembling the pin with the arm in suchmanner that it cannot be lost in transit. For this purpose, the arm 13is formed on its under side with a recess in which the pin may be nestedand clamped against the top of the barrel. This recess may take the formof a slot 31 having beveled or concave side walls 32 for engaging thecranlepin. The slot is longer than the stud or sleeve, so that thecrank-pin may be'nested in the recess between the arm and head of thebarrel, and thus be clamped between the last-mentioned parts.

In practice, the agitator may be located within the barrel, and the heador cap of the arm (with thepacking 20 in place) located overthe opening15 in the head of the .barrel, with the clutch members 24, 25, engagingtheend of the agitator. The crank-pin, which is then detached ordismounted, is placed in the recess in the arm, and Wood screwsor otherfastenings are passed through the holes 22,-23, so as secure ly tofasten the head in place and to tightly close the opening 15. Thecrank-pin is thus securely clamped' against' dislocation in the recess,

'and between thearm and the barrel. If desired, a fourth wood screw maybe driven through 'the' aperture 18 in the end of the arm into the headof the barrel, but this ordinarily isunnecessary, `When the barrel'a'r'rives `'at' its destination, the wood screws are removed, thecrank-pin is secured to the end of the arm by screwing the stud 26 intothe threaded aperture 18, and the arm may now be moved about its axis tooperate the agitator.

Of course, other suitable meansmay be cmployed for securing the handlein place. In fact, the cap be threaded to screw into a threaded openingin the head of the barrel or container, as shown in my said copendingapplication.

It will be noted, from an examinaton of Figure 1, that, when the crankpin is nested in the recess in the arm and thereby clamped in place, allportions of the arm are located below the plane at the edge of the chineof the barrel, so that "there is little likelihood of the arm beingbroken or otherwise injured.
